15. These, then, “were born not of the will of the flesh, nor of the will of man, but of God.” But that men might be born of God, God was first born of them. For Christ is God, and Christ was born of men. It was only a mother, indeed, that He sought upon earth; because He had already a Father in heaven: He by whom we were to be created was born of God, and He by whom we were to be re-created was born of a woman. Marvel not, then, O man, that thou art made a son by grace, that thou art born of God according to His Word. The Word Himself first chose to be born of man, that thou mightest be born of God unto salvation, and say to thyself, Not without reason did God wish to be born of man, but because He counted me of some importance, that He might make me immortal, and for me be born as a mortal man. When, therefore, he had said, “born of God,” lest we should, as it were, be filled with amazement and trembling at such grace, at grace so great as to exceed belief that men are born of God, as if assuring thee, he says, “And the Word was made flesh, and dwelt among us.” Why, then, dost thou marvel that men are born of God? Consider God Himself born of men: “And the Word was made flesh, and dwelt among us.”
